Applications for Citizenship in the Context of the Brazilian Digital Television System João Benedito dos Santos Junior 1 , Kim Pontes Braga 1 , Danilo Carneiro de Souza 1 , Marcus Vinicius Gouvea Lourenço 1 , Rafael Afonso Cancian 1 1 Pontifical Catholic University of Minas Gerais – PUC Minas Departament of Computing - Interactive Digital Television Laboratory – TVDILab Poços de Caldas – MG, Brazil joao@pucpcaldas.br Extended abstract This work presents some contributions towards Interactive Digital Television (iDTv), focusing on the central issue of the interactivity channel on the context of the Brazilian Digital Television System Terrestrial (SBTVD-T or ISDB-TB), highlighting the necessary infrastructure, applications and services that can help with the challenges of promoting digital inclusion in Brazil. As a product of this investigation, a prototype of a Service Guide to support the promotion of citizenship through digital inclusion is under development. In the context of SBTVD-T, applications can be built to explore different forms of services, ranging from the popular EPG (Electronic Program Guides) and voting polls, and reaching the portals of public services, by example [1]. The life cycle begins with the production and distribution of audio and video streams that are multiplexed to form structures in Transport Stream (TS), besides objects carousel (audio, video, images, text, graphics and executable/interpreted applications). These structures are received and presented at the access terminal of the viewer/user. The last stage is focused on the interaction of the viewer/user with resident applications without using the back channel; the interaction is completed using the back channel via any communication infrastructure [2]. The applications of the Service Guide for Citizenship will be embedded in equipment receptors (settop boxes), reaching the homes of viewers/users. A summary of applications is presented in the following: a) Understanding Dengue (a typical disease that occurs in Brazil); b) Doctors in Your Home; c) Health Tests; d) In Case of Emergency; e) Comprehending the Public Administration; f) The Community Sends News; g) Banking; h) Repository of News; i) The School on TV. New features and applications can be developed and aggregated into the guide [3]. Tests are being conducted both in the laboratory and real broadcast environment, created by broadcaster partners. Results of these tests and developments will be reported in further works. References 1. VRBA, V.; CVRK, L.; SYKORA, M. Framework for Digital TV Applications.
